I'm interested in cutting different designs into 14k gold. I've went from laser, to water jet, to cnc router and can't seem to find the right fit. We're interested in making very small designs such as hearts, names, and even circles into the metal. I'm hoping that someone can steer me in the right direction as to what machinery would be the best to use. The parts we're cutting are apprximately 0.3 mm in thickness and are 1 inch x 1inch in diameter. Any information would be helpful.

May be the perfect job for something like a Taig CNC mill.

If you're always working with small stuff then the Taig would be a good choice with the CNC option. Really depends if you want a machine where all you have to do is create the part in CAD, transfer to your CAM and hit the "do it" button.

i'm going to look into it now.

Not cheap, but checkout www.minitech.com

those are sherline or a copy of them. good stuff but not worth 20k

machining gold gets quite expensive in chips....that's why people cast it. You can certainly use a cnc to do the cores though
